Cannot perform a handshake with google`s cloud speech-to-text on ESP32. [PK - The pubkey tag or value is invalid (only RSA and EC are supported)]

Question

I am trying to establish a connection with speech.googleapis.com. I am using the code from https://github.com/MhageGH/esp32_CloudSpeech/tree/master/esp32_CloudSpeech. I modified the network_param.h, so that certificate is set right. I also created the ApiKey on google cloud and added it to the network_param.h.

I try to create CloudSpeechClient() using the API enum. CloudSpeechClient* cloudSpeechClient = new CloudSpeechClient(USE_APIKEY);

I am stuck with this error saying that pubkey tag or value is invalid.

Not sure how to format it in a better way - maybe image will be better. Traces in image format

I tried changing the certificate and re-generating the API code. I tried puuting less restriction on the API key. I expected it to connect smoothly :/.
